Improvement in water-wheels



GARDNER COX, OF PIERREPONT, NEW YORKr' Letters Patent No. 92,017, dated June 29, 1869.

IMPROVEMENT N WATER-WHEELS,

The Schedule referred to in these Letters Patent and making part of the saine.

To all whom it may concern: l

Be it known that I, GARDNER 00X, of Pierrepont, in Jthe county of St. Lawrence, and State of New York, have invented a new and valuable Improvement in \Vatex'-\Vheels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference heinghad to the annexed drawings, making a part of this specification, and to the letter-sof' reference marked thereon.

My invention has relation to Water-wheels; and

It consists mainly in the construction and arrangement, in a novel manner, of devices by whieh the gates of a turbine wheel may be easily and expeditiously opened or closed at will.

The letter A, of the drawings, represents the bottom plate; letter B, the upper pla-te; and letters C, the gates, ot' my turbine water-wheel.

These gates are pi'xoted, as shown, to the plates respectively, the upper ends ot` the pivots working aud resting in the curved slots c of the upper plate, as represented.

The letter E is a representation of the shaft of the wheel; and letters F, of the chutes or aprons that conduct the water to the gates.

The letter P renresentsa plate or bar, axed to the upper surface of plate B, as shown, and having a ratchet-head thereto, to operate with the pinion H, next mentioned. y

rIhe letter H represents a pinion, aixed to an up-l right post, that rotates in suitable journals or pivotblocks, contiguous to plate B.

The oitice ot' this ratchet-headed plate, post, and pinion, is to c onjointly serve as the means -by which the plate B maybe moved to the right or left, and thereby the gates be opened or closed, as vmay be desirable. v

lo open the gates, the pinion H is turned to the left. To close the gates, I turn-said pinion to the right.

C Zaifm,

What I claim as my invention, and desire to secure by Letters Patent, is,-

'Ihe plates A, l, and G, gates C, chutes F, and pinion H, when constructed and arranged to operate substantially as and for the purposes specified.

GARDNER COX.
